Lighter springs would help all types of shooters (long as the primer goes bang :grin: )
The correct term is slip-hammering and that is different from fanning which is not allowed.
Slip-hammering is where your thumb of the hand holding the revolver slips off the side of the hammer (left side for right hander) as you hold the trigger to the rear. Fanning is using the other hand to fan the hammer back. It is felt with fanning you are not in complete control of the firearm and there is the increased risk of shots going in unsafe directions.
As to times, get the mechanics of the hold down and practice, practice, etc. If you start out doing it correctly your time will come down. Don't try to rush this learning. Research states that you have to do something about 3000 times before you have muscle-memory developed. And that is a bunch of times no matter who's counting.
